8 0

Answer:

Explanation:

The first law of Thermodynamics is known as Conservation because it explains that energy is always maintained within a closed system and cannot be created or destroyed. Therefore, this is observed when there is no longer change in temperature in a system. Mainly because the energy is not being transferred to and from another system. Without this transfer of energy, the energy itself gets conserved within the system and the temperature no longer fluctuates.

A container is filled with a mixture of gases:
Crazy boy [7]

Answer:

The pressure of Cl2 is 1, 55 atm.

Explanation:

The sum of the partial pressures of the gases that make up a gaseous mixture is equal to the total pressure of said mixture, according to Dalton's law:

P total = P02 + P N2 + P Cl2

P Cl2= P total - P02 - P N2=3,30 atm-1,0 atm -0,75 atm=<em>1,55 atm</em>
